Abstract:Finite difference method was used to calculate the macroscopic transportation phenomena(including temperature and concentration fields) of Al-7%Si(mass fraction) alloy. On the basis of the results,coupled with local area magnification, the nucleation and growth of primary α-phase of Al-7%Si were simulated. Relating the growth process of α-phase of Al-7%Si alloy in space with structures of a sample section, the morphology and precipitating process of primary α-phase of Al-7%Si alloy was simulated. The results are in good agreement with those obtained experimentally.
Key words: Al-7%Si alloy; macroscopic transportation; primary α-phase; simulation
